Thanks@IrvSp I'll try the connecting-starting process again. I have the Ethernet cable from the modem to the WAN of the router. And another Ethernet cable from the router to the PC. If I didn'tsee...

@Kerrith Thanks Tony, I've tried your suggestions. Strange because Spectrum's speed test consistently shows 425Mbps.

I have the AX6000 connected via Ethernet cable from the fastest Spectrum modem. Internet speed is about 425 Mbps. @ArcherC8

URL: tp-link, Basic tab > Speed test: Mostly it hovers around 2-3 ocassionally 4 kbps. I don't understand why or what it should be? My Spectrum account, via their modem, internet speed reads 437 Mbps...
